📏 Dosage & Administration
2 DOSAGE AND ADMINISTRATION Capsules must be taken whole. ( 2.1 ) Take consistently every morning at the same time on an empty stomach at least 1 hour before a meal or at least 2 hours after a meal. ( 2.1 ) Avoid eating grapefruit or drinking grapefruit juice or alcohol. ( 2.1 ) African-American patients and patients with severe hepatic impairment may require dosing adjustments. ( 2.3 ) Frequent monitoring of trough concentrations is recommended. ( 2.4 ) For complete dosing information, see Full Prescribing Information. MMF = Mycophenolate mofetil Recommended Tacrolimus Extended-Release Capsules Initial Dosage Patient Population Initial Oral Dosage Whole Blood Trough Concentration Range ADULT With basiliximab, MMF and steroids 0.15 mg/kg to 0.2 mg/kg once daily prior to reperfusion or within 48 hours of completion of transplant Month 1: 7 ng/mL to 15 ng/mL Month 2 to Month 6: 5 ng/mL to 15 ng/mL More than 6 Months: 5 ng/mL to 10 ng/mL With MMF and steroids, without basiliximab induction First dose (pre-operative): 0.1 mg/kg, within 12 hours prior to reperfusion Subsequent doses (post-operative): 0.2 mg/kg once daily at least 4 hours after pre-operative dose and within 12 hours after reperfusion Month 1: 10 ng/mL to 15 ng/mL Month 2 to Month 6: 5 ng/mL to 15 ng/mL More than 6 Months: 5 ng/mL to 10 ng/mL 2.1 Important Administration Instructions Tacrolimus extended-release capsules should not be used without the supervision by a physician with experience in immunosuppressive therapy. Tacrolimus extended-release capsules is not interchangeable or substitutable for tacrolimus extended-release tablets, tacrolimus immediate-release capsules or tacrolimus for oral suspension. Under or overexposure to tacrolimus may result in graft rejection or other serious adverse reactions. Changes between tacrolimus immediate-release and extended-release dosage forms must occur under physician supervision [see Warnings and Precautions ( 5.4 )]. Advise patients to swallow tacrolimus extended-release capsules whole with liquid; patients must not chew, divide, or crush the capsules. Tacrolimus extended-release capsules should be taken consistently every morning at the same time to ensure consistent and maximum possible drug exposure, on an empty stomach at least 1 hour before a meal, or at least 2 hours after a meal [see Clinical Pharmacology ( 12.3 )]. If a dose is missed, the dose may be taken up to 14 hours after the scheduled time (i.e., for a missed 8:00 AM dose, a dose may be taken by 10:00 PM). Beyond the 14-hour time frame, the patient should wait until the usual scheduled time the following morning to take the next regular daily dose. Instruct the patient not to double the next dose. Advise patients to avoid eating grapefruit or drinking grapefruit juice or alcoholic beverages while taking tacrolimus extended-release capsules [see Drug Interactions ( 7.2 )]. Therapeutic drug monitoring is recommended for all patients receiving tacrolimus extended-release capsules [see Dosage and Administration ( 2.4 )] . 2.2 Dosage Recommendations for Kidney Transplant Patients Table 1 includes the recommended starting tacrolimus extended-release capsules dosages and whole blood trough concentration ranges; the observed trough concentrations are shown in another section of the Full Prescribing Information [see Clinical Studies ( 14 )] . Titrate the tacrolimus extended-release capsules dosage based on clinical assessments of rejection and tolerability, and to achieve target trough concentration ranges [see Dosage and Administration ( 2.4 ) and Warnings and Precautions ( 5.6 , 5.7 , 5.10 , 5.11 )] . Table 1: Recommended Starting Daily Dosage Regimen of Tacrolimus Extended-Release Capsules MMF = mycophenolate mofetil Recommended Tacrolimus Extended-Release Capsules Initial Dosage* Patient Population Initial Oral Dosage Whole Blood Trough Concentration Range ADULT With basiliximab, MMF and steroids 0.15 mg/kg to 0.2 mg/kg once daily prior to reperfusion or within 48 hours of completion of transplant • Month 1: 7 ng/mL to 15 ng/mL • Month 2 to Month 6: 5 ng/mL to 15 ng/mL • More than 6 Months: 5 ng/mL to 10 ng/mL With MMF and steroids, without basiliximab induction • First dose (pre-operative): 0.1 mg/kg, within 12 hours prior to reperfusion • Subsequent doses (post-operative): 0.2 mg/kg once daily at least 4 hours after pre-operative dose and within 12 hours after reperfusion • Month 1: 10 ng/mL to 15 ng/mL • Month 2 to Month 6: 5 ng/mL to 15 ng/mL • More than 6 Months: 5 ng/mL to 10 ng/mL Pediatric use information is approved for Astellas Pharma US, Inc.'s ASTAGRAF XL (tacrolimus extended-release capsules). However, due to Astellas Pharma US, Inc.'s marketing exclusivity rights, this drug product is not labeled with that information. 2.3 Dosage Modifications for African-American Patients, Patients with Hepatic Impairment, and Drug Interactions African-American patients, compared to Caucasian patients, may need to be titrated to higher tacrolimus extended-release capsules dosages to attain comparable trough concentrations [see Clinical Pharmacology ( 12.3 ) and Clinical Studies ( 14 )] . Patients with severe hepatic impairment (Child-Pugh ≥ 10) may require a lower starting dosage of tacrolimus extended-release capsules, due to the reduced clearance and prolonged half-life [see Clinical Pharmacology ( 12.3 )]. Dose adjustments of tacrolimus extended-release capsules may be necessary when administered concomitantly with CYP3A inducers or CYP3A inhibitors or cannabidiol [see Warnings and Precautions ( 5.10 , 5.15 ) and Drug Interactions ( 7.2 , 7.3 )]. 2.4 Therapeutic Drug Monitoring Measure tacrolimus whole blood trough concentrations at least two times on separate days during the first week after initiation of dosing and after a change in dosage, after a change in co-administration of CYP3A4 inducers and/or inhibitors or cannabidiol [see Drug Interactions (7.2 , 7.3 )] , or after a change in renal or hepatic function. When interpreting measured concentrations, consider that the time to achieve tacrolimus steady state is approximately 7 days after initiating or changing the tacrolimus extended-release capsules dose. Monitor tacrolimus whole blood trough concentrations using a validated assay [e.g., immunoassays or high performance liquid chromatography with tandem mass spectrometric detection (HPLC/MS/MS)]. The immunosuppressive activity of tacrolimus is mainly due to the parent drug rather than to its metabolites. Immunoassays may react with metabolites as well as the parent drug. Therefore, whole blood tacrolimus trough concentrations obtained with immunoassays may be numerically higher than concentrations obtained with an assay using HPLC/MS/MS. Comparison of the whole blood tacrolimus trough concentrations of patients to those described in the prescribing information and other published literature must be made with knowledge of the assay method(s) employed.

( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact eVenus Pharmaceutical Laboratories, Inc. at 1-609-395-8625 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Studies Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. In addition, the clinical trials were not designed to establish comparative differences across study arms with regards to the adverse reactions discussed below. Kidney transplant patients were treated with tacrolimus extended-release capsules (N=214) or tacrolimus immediate-release product (N=212) and concomitant immunosuppressants (median duration of exposure of 12 months) in a randomized, open-label, active-controlled trial of mostly U.S. patients (Study 1) [see Clinical Studies ( 14.1 )] . The types of adverse reactions seen in Study 1 were similar to the adverse reactions seen in Study 2 [non-U.S. trial in kidney transplant patients treated with tacrolimus extended-release capsules (N=331) or tacrolimus immediate-release product (N=336) and concomitant immunosuppressants] [see Clinical Studies ( 14.2 )] . In Study 1, the proportion of patients who discontinued treatment due to adverse reactions was 9% and 11% in the tacrolimus extended-release capsules and tacrolimus immediate-release treatment groups, respectively, through 12 months of treatment. The most common adverse reactions leading to discontinuation in tacrolimus extended-release capsules-treated patients were related to infections or renal/urinary disorders. Infections The overall incidence of infections, serious infections, and infections with identified etiology reported in patients treated with the tacrolimus extended-release capsules or tacrolimus immediate-release product in Study 1 are shown in Table 2 . Table 2: Percentage of Patients with Infections in Study 1 Study 1 was not designed to support comparative claims of tacrolimus extended-release capsules compared to tacrolimus immediate-release product for the adverse reactions reported in this table.

However, due to Astellas Pharma US, Inc.'s marketing exclusivity rights, this drug product is not labeled with that information. 6.2 Postmarketing Experience The following adverse reactions have been reported from marketing experience with tacrolimus in the U.S. and outside the U.S. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. These reactions have been chosen for inclusion due to either their seriousness, frequency of reporting or causal connection to tacrolimus extended-release capsules: Blood and Lymphatic System Disorders: Agranulocytosis, disseminated intravascular coagulation, hemolytic uremic syndrome, febrile neutropenia, pancytopenia, pure red cell aplasia [see Warnings and Precautions ( 5.13 )] , coagulopathy, thrombotic thrombocytopenic purpura, prolonged activated partial thromboplastin time, decreased blood fibrinogen Cardiac Disorders: Cardiac arrest, myocardial infarction, ventricular fibrillation, congestive cardiac failure, hypertrophic cardiomyopathy, pericardial effusion, angina pectoris, supraventricular extrasystoles, supraventricular tachycardia, bradycardia, Torsades de pointes , QT prolongation Ear Disorders: Hearing loss Eye Disorders: Blindness, optic neuropathy, optic atrophy, photophobia Gastrointestinal Disorders: Gastrointestinal hemorrhage, gastrointestinal perforation, pancreatitis, peritonitis, stomach ulcer, intestinal obstruction, ascites, colitis, ileus, impaired gastric emptying, dysphagia Hepatobiliary Disorders: Hepatic failure, hepatic necrosis, cirrhosis, cholangitis, venoocclusive liver disease, bile duct stenosis, hepatic steatosis, jaundice Hypersensitivity Reactions: Hypersensitivity, Stevens-Johnson syndrome, toxic epidermal necrolysis, urticaria Immune System Disorders: Graft versus host disease (acute and chronic) Investigations: Increased international normalized ratio Metabolism and Nutrition Disorders: Hypoproteinemia Musculoskeletal and Connective Tissue Disorders: Rhabdomyolysis, myalgia, polyarthritis, pain in extremity including Calcineurin-Inhibitor Induced Pain Syndrome (CIPS) Neoplasms: Lymphoma including EBV-associated lymphoproliferative disorder, hepatosplenic T-cell lymphoma, PTLD [see Warnings and Precautions ( 5.1 )] , leukemia, melanoma Nervous System Disorders: Cerebral infarction, progressive multifocal leukoencephalopathy (PML) sometimes fatal [see Warnings and Precautions ( 5.2 )] , posterior reversible encephalopathy syndrome (PRES) [see Warnings and Precautions ( 5.7 )] , coma, status epilepticus, quadriplegia, flaccid paralysis, hemiparesis, aphasia, syncope, carpal tunnel syndrome, nerve compression, mutism, dysarthria, somnolence Psychiatric Disorders: Mental status changes Renal and Urinary Disorders: Hemorrhagic cystitis, hematuria, urinary retention, urinary incontinence Respiratory, Thoracic and Mediastinal Disorders: Interstitial lung disease, pulmonary hypertension, lung infiltration, rhinitis allergic, hiccups Skin and Subcutaneous Tissue Disorders: Hyperpigmentation, photosensitivity Vascular Disorders: Hemorrhage
⚠️ Warnings & Precautions
5 WARNINGS AND PRECAUTIONS Not Interchangeable with Other Tacrolimus Products-Medication Errors: Instruct patients or caregivers to recognize the appearance of tacrolimus extended-release capsules. ( 5.4 ) New onset diabetes after transplant: Monitor blood glucose. ( 5.5 ) Nephrotoxicity (acute and/or chronic): May occur due to tacrolimus extended-release capsules, drug interactions, concomitant nephrotoxic drugs. Monitor renal function; consider dosage reduction. ( 5.6 ) Neurotoxicity: Including risk of posterior reversible encephalopathy syndrome (PRES), monitor for neurologic abnormalities; reduce dosage or discontinue tacrolimus extended-release capsules. ( 5.7 ) Hyperkalemia: Risk may be increased with other agents associated with hyperkalemia; monitor serum potassium levels. ( 5.8 ) Hypertension: May require antihypertensive therapy; monitor relevant drug interactions. ( 5.9 ) QT prolongation: Consider obtaining electrocardiograms and monitoring electrolytes in patients at high risk. ( 5.11 ) Immunizations: Avoid live vaccines. ( 5.12 ) Pure red cell aplasia: Consider discontinuation of tacrolimus extended-release capsules. ( 5.13 ) Thrombotic Microangiopathy, Including Hemolytic Uremic Syndrome and Thrombotic Thrombocytopenic Purpura: May occur, especially in patients with infections and certain concomitant medications. ( 5.14 ) 5.1 Lymphoma and Other Malignancies Immunosuppressants, including tacrolimus extended-release capsules, increase the risk of developing lymphomas and other malignancies, particularly of the skin . The risk appears to be related to the intensity and duration of immunosuppression rather than to the use of any specific agent. Examine patients for skin changes and advise to avoid or limit exposure to sunlight and UV light by wearing protective clothing and using a broad-spectrum sunscreen with a high protection factor. Post-transplant lymphoproliferative disorder (PTLD), associated with Epstein-Barr Virus (EBV), has been reported in immunosuppressed organ transplant patients. The risk of PTLD appears greatest in patients who are EBV seronegative, a population which includes many young children. Monitor EBV serology during treatment. 5.2 Serious Infections Immunosuppressants, including tacrolimus extended-release capsules, increase the risk of developing bacterial, viral, fungal, and protozoal infections, including opportunistic infections. These infections may lead to serious, including fatal, outcomes. Serious viral infections reported include: Polyomavirus-associated nephropathy (especially due to BK virus infection) JC virus-associated progressive multifocal leukoencephalopathy (PML) Cytomegalovirus (CMV) infections: CMV seronegative transplant patients who receive an organ from a CMV seropositive donor are at highest risk of CMV viremia and CMV disease. Monitor for the development of infection and adjust the immunosuppressive regimen to balance the risk of rejection with the risk of infection [see Adverse Reactions ( 6.1 , 6.2 )] . 5.3 Increased Mortality in Female Liver Transplant Patients In a clinical trial of 471 liver transplant patients randomized to tacrolimus extended-release capsules or tacrolimus immediate-release product, mortality at 12 months was 10% higher among the 76 female patients (18%) treated with tacrolimus extended-release capsules compared to the 64 female patients (8%) treated with tacrolimus immediate-release product. Tacrolimus extended-release capsules is not approved for the prophylaxis of organ rejection in patients who received a liver transplant. 5.4 Not Interchangeable with Other Tacrolimus Products - Medication Errors Medication errors, including substitution and dispensing errors, between tacrolimus immediate-release products and tacrolimus extended-release capsules were reported outside the U.S. This led to serious adverse reactions, including graft rejection, or other adverse reactions due to under- or over-exposure to tacrolimus. Tacrolimus extended-release capsules is not interchangeable or substitutable for tacrolimus extended-release tablets, tacrolimus immediate-release capsules or tacrolimus for oral suspension. Changes between tacrolimus immediate-release and extended-release dosage forms must occur under physician supervision. Instruct patients and caregivers to recognize the appearance of tacrolimus extended-release capsules [see Dosage Forms and Strengths ( 3 )] and to confirm with the healthcare provider if a different product is dispensed or if dosing instructions have changed. 5.5 New Onset Diabetes After Transplant Tacrolimus extended-release capsules caused new onset diabetes after transplant (NODAT) in kidney transplant patients, which may be reversible in some patients. African-American and Hispanic kidney transplant patients are at an increased risk. Monitor blood glucose concentrations and treat appropriately [see Adverse Reactions ( 6.1 ) and Use in Specific Populations ( 8.8 )] . 5.6 Nephrotoxicity due to Tacrolimus Extended-Release Capsules and Drug Interactions Tacrolimus extended-release capsules, like other calcineurin-inhibitors, can cause acute or chronic nephrotoxicity in transplant patients due to its vasoconstrictive effect on renal vasculature, toxic tubulopathy and tubular-interstitial effects. Acute renal impairment associated with tacrolimus toxicity can result in high serum creatinine, hyperkalemia, decreased secretion of urea and hyperuricemia, and is usually reversible. In patients with elevated serum creatinine and tacrolimus whole blood trough concentrations greater than the recommended range, consider dosage reduction or temporary interruption of tacrolimus administration. The risk for nephrotoxicity may increase when tacrolimus extended-release capsules is concomitantly administered with CYP3A inhibitors (by increasing tacrolimus whole blood concentrations) or drugs associated with nephrotoxicity (e.g., aminoglycosides, ganciclovir, amphotericin B, cisplatin, nucleotide reverse transcriptase inhibitors, protease inhibitors). When tacrolimus is used concurrently with other known nephrotoxic drugs, monitor renal function and tacrolimus blood concentrations, and adjust dose of both tacrolimus and/or concomitant medications during concurrent use [see Adverse Reactions ( 6.1 , 6.2 ) and Drug Interactions ( 7.2 )]. 5.7 Neurotoxicity Tacrolimus extended-release capsules may cause a spectrum of neurotoxicities. The most severe neurotoxicities include posterior reversible encephalopathy syndrome (PRES), delirium, seizure and coma; others include tremors, paresthesias, headache, mental status changes, and changes in motor and sensory functions [see Adverse Reactions ( 6.1 , 6.2 )] . As symptoms may be associated with tacrolimus whole blood trough concentrations at or above the recommended range, monitor for neurologic symptoms and consider dosage reduction or discontinuation of tacrolimus extended-release capsules if neurotoxicity occurs. 5.8 Hyperkalemia Mild to severe hyperkalemia, which may require treatment, has been reported with tacrolimus including tacrolimus extended-release capsules. Concomitant use of agents associated with hyperkalemia (e.g., potassium-sparing diuretics, ACE inhibitors, angiotensin receptor blockers) may increase the risk for hyperkalemia [see Adverse Reactions ( 6.1 )] . Monitor serum potassium levels periodically during treatment. 5.9 Hypertension Hypertension is a common adverse reaction of tacrolimus extended-release capsules therapy and may require antihypertensive therapy [see Adverse Reactions ( 6.1 )] . Some antihypertensive drugs can increase the risk for hyperkalemia [see Warnings and Precautions ( 5.8 )] . Calcium-channel blocking agents may increase tacrolimus blood concentrations and require dosage reduction of tacrolimus extended-release capsules [see Drug Interactions ( 7.2 )] . 5.10 Risk of Rejection with Strong CYP3A Inducers and Risk of Serious Adverse Reactions with Strong CYP3A Inhibitors The concomitant use of strong CYP3A inducers may increase the metabolism of tacrolimus, leading to lower whole blood trough concentrations and greater risk of rejection. In contrast, the concomitant use of strong CYP3A inhibitors may decrease the metabolism of tacrolimus, leading to higher whole blood trough concentrations and greater risk of serious adverse reactions (e.g., neurotoxicity, QT prolongation) [see Warnings and Precautions ( 5.7 , 5.11 )] . Therefore, adjust tacrolimus extended-release capsules dose and monitor tacrolimus whole blood trough concentrations when co-administering tacrolimus extended-release capsules with strong CYP3A inhibitors (e.g., including, but not limited to, telaprevir, boceprevir, ritonavir, ketoconazole, itraconazole, voriconazole, clarithromycin) or strong CYP3A inducers (e.g., including, but not limited to, rifampin, rifabutin) [see Dosage and Administration ( 2.4 ) and Drug Interactions ( 7.2 )] . A rapid, sharp rise in tacrolimus levels has been reported after co-administration with a strong CYP3A4 inhibitor, clarithromycin, despite an initial reduction of tacrolimus dose. Early and frequent monitoring of tacrolimus whole blood trough levels is recommended [see Drug Interactions (7.2) ] . 5.11 QT Prolongation Tacrolimus extended-release capsules may prolong the QT/QTc interval and cause Torsades de pointes . Avoid tacrolimus extended-release capsules in patients with congenital long QT syndrome. Consider obtaining electrocardiograms and monitoring electrolytes (magnesium, potassium, calcium) periodically during treatment in patients with congestive heart failure, bradyarrhythmias, those taking certain antiarrhythmic medications or other products that lead to QT prolongation, and those with electrolyte disturbances (e.g., hypokalemia, hypocalcemia, or hypomagnesemia). When co-administering tacrolimus extended-release capsules with other substrates and/or inhibitors of CYP3A, especially those that also have the potential to prolong the QT interval, a reduction in tacrolimus extended-release capsules dosage, monitoring of tacrolimus whole blood concentrations, and monitoring for QT prolongation is recommended [see Dosage and Administration ( 2.4 ) and Drug Interactions ( 7.2 )] . 5.12 Immunizations Whenever possible, administer the complete complement of vaccines before transplantation and treatment with tacrolimus extended-release capsules. Avoid the use of live attenuated vaccines during treatment with tacrolimus extended-release capsules (e.g., intranasal influenza, measles, mumps, rubella, oral polio, BCG, yellow fever, varicella, and TY21a typhoid vaccines). Inactivated vaccines noted to be safe for administration after transplantation may not be sufficiently immunogenic during treatment with tacrolimus extended-release capsules. 5.13 Pure Red Cell Aplasia Cases of pure red cell aplasia (PRCA) have been reported in patients treated with tacrolimus. All of these patients reported risk factors for PRCA such as parvovirus B19 infection, underlying disease, or concomitant medications associated with PRCA. A mechanism for tacrolimus-induced PRCA has not been elucidated. If PRCA is diagnosed, consider discontinuation of tacrolimus extended-release capsules. 5.14 Thrombotic Microangiopathy (TMA) Including Hemolytic Uremic Syndrome and Thrombotic Thrombocytopenic Purpura Cases of thrombotic microangiopathy (TMA), including hemolytic uremic syndrome (HUS) and thrombotic thrombocytopenic purpura (TTP), have been reported in patients treated with tacrolimus extended-release capsules TMA may have a multifactorial etiology. Risk factors for TMA that can occur in transplant patients include, for example, severe infections, graft-versus-host disease (GVHD), Human Leukocyte Antigen (HLA) mismatch, the use of calcineurin inhibitors and mammalian target of rapamycin (mTOR) inhibitors. These risk factors may, either alone or combined, contribute to the risk of TMA. In patients with signs and symptoms of TMA, consider tacrolimus as a risk factor. Concurrent use of tacrolimus and mTOR inhibitors may contribute to the risk of TMA. 5.15 Cannabidiol Drug Interactions When cannabidiol and tacrolimus extended-release capsules are co-administered, closely monitor for an increase in tacrolimus blood levels and for adverse reactions suggestive of tacrolimus toxicity. A dose reduction of tacrolimus extended-release capsules should be considered as needed when tacrolimus extended-release capsules is co-administered with cannabidiol [see Dosage and Administration (2.4) and Drug Interactions (7.3) ] .
🔄 Drug Interactions
7 DRUG INTERACTIONS Risk of rejection with strong CYP3A inducers and risk of serious adverse reactions with strong CYP3A inhibitors: Adjust dose and monitor tacrolimus concentrations. ( 2.4 , 5.10 , 7.2 ) Therapeutic drug monitoring and dose reduction for tacrolimus extended-release capsules should be considered when tacrolimus extended-release capsules is co-administered with cannabidiol. ( 2.4 , 5.15 , 7.3 ) See Full Prescribing Information for clinically significant drug interactions. ( 7.1 , 7.2 , 7.3 ) 7.1 Mycophenolic Acid When tacrolimus extended-release capsules is prescribed with a given dose of a mycophenolic acid (MPA) product, exposure to MPA is higher with tacrolimus extended-release capsules co-administration than with cyclosporine co-administration with MPA, because cyclosporine interrupts the enterohepatic recirculation of MPA while tacrolimus does not. Monitor for MPA-associated adverse reactions and reduce the dose of concomitantly administered mycophenolic acid products as needed. 7.2 Effects of Other Drugs on Tacrolimus Extended-Release Capsules Table 5 displays the effects of other drugs on tacrolimus extended-release capsules. Table 5: Effects of Other Drugs/Substances on Tacrolimus Extended-Release Capsules Tacrolimus extended-release capsules dosage adjustment recommendation based on observed effect of co-administered drug on tacrolimus exposures [see Clinical Pharmacology ( 12.3)] , literature reports of altered tacrolimus exposures, or the other drug’s known CYP3A inhibitor/inducer status. Drug/Substance Class or Name Drug Interaction Effect Recommendations Grapefruit or grapefruit juice High dose or double strength grapefruit juice is a strong CYP3A inhibitor; low dose or single strength grapefruit juice is a moderate CYP3A inhibitor. May increase tacrolimus whole blood trough concentrations and increase the risk of serious adverse reactions (e.g., neurotoxicity, QT prolongation) [see Warnings and Precautions ( 5.7 , 5.10 , 5.11 )] . Avoid grapefruit or grapefruit juice. Alcohol May increase the rate of tacrolimus release and increase the risk of serious adverse reactions (e.g., neurotoxicity, QT prolongation ) [see Warnings and Precautions ( 5.7 , 5.10 , 5.11 )] . Avoid alcoholic beverages. Strong CYP3A Inducers Strong CYP3A inhibitor/inducer, based on reported effect on exposures to tacrolimus along with supporting in vitro CYP3A inhibitor/inducer data, or based on drug-drug interaction studies with midazolam (sensitive CYP3A probe substrate). : Antimycobacterials (e.g., rifampin, rifabutin), anticonvulsants (e.g., phenytoin, carbamazepine and phenobarbital), St John’s wort May decrease tacrolimus whole blood trough concentrations and increase the risk of rejection [see Warnings and Precautions ( 5.10 )] . Increase tacrolimus extended-release capsules dose and monitor tacrolimus whole blood trough concentrations [see Dosage and Administration ( 2.3 , 2.4 ) and Clinical Pharmacology ( 12.3 )] . Strong CYP3A Inhibitors : Protease inhibitors (e.g., nelfinavir, telaprevir, boceprevir, ritonavir), azole antifungals (e.g., voriconazole, posaconazole, itraconazole, ketoconazole), antibiotics (e.g., clarithromycin, troleandomycin, chloramphenicol), nefazodone, letermovir, Schisandra sphenanthera extracts May increase tacrolimus whole blood trough concentrations and increase the risk of serious adverse reactions (e.g., neurotoxicity, QT prolongation). A rapid, sharp rise in tacrolimus levels may occur early, despite an immediate reduction of tacrolimus dose [see Warnings and Precautions ( 5.7 , 5.10 , 5.11 )] . Reduce tacrolimus extended-release capsules dose (for voriconazole and posaconazole, give one-third of the original dose) and adjust dose based on tacrolimus whole blood trough concentrations [see Dosage and Administration ( 2.3 , 2.4 ) and Clinical Pharmacology ( 12.3 )] . Early and frequent monitoring of tacrolimus whole blood trough levels should start within 1-3 days and continue monitoring as necessary [see Warnings and Precautions (5.10) ] . Mild or Moderate CYP3A Inhibitors: Clotrimazole, antibiotics (e.g., verapamil, diltiazem, nifedipine, nicardipine), amiodarone, danazol, ethinyl estradiol, cimetidine, lansoprazole and omeprazole May increase tacrolimus whole blood trough concentrations and increase the risk of serious adverse reactions (e.g., neurotoxicity, QT prolongation) [see Warnings and Precautions ( 5.7 , 5.10 , 5.11 )] . Monitor tacrolimus whole blood trough concentrations and reduce tacrolimus extended-release capsules dose if needed [see Dosage and Administration ( 2.3 , 2.4 ) and Clinical Pharmacology ( 12.3 )] . Other drugs, such as: Magnesium and aluminum hydroxide antacids Metoclopramide May increase tacrolimus whole blood trough concentrations and increase the risk of serious adverse reactions (e.g., neurotoxicity, QT prolongation) [see Warnings and Precautions ( 5.7 , 5.10 , 5.11 )] . Monitor tacrolimus whole blood trough concentrations and reduce tacrolimus extended-release capsules dose if needed [see Dosage and Administration ( 2.3 , 2.4 ) and Clinical Pharmacology ( 12.3 )] . Mild or Moderate CYP3A Inducers Methylprednisolone, prednisone May decrease tacrolimus whole blood trough concentrations. Monitor tacrolimus whole blood trough concentrations and adjust tacrolimus extended-release capsules dose if needed [see Dosage and Administration ( 2.3 , 2.4 )] . Caspofungin May decrease tacrolimus whole blood trough concentrations. Monitor tacrolimus whole blood trough concentrations and adjust tacrolimus extended-release capsules dose if needed [see Dosage and Administration (2.3 , 2.4) ] . Direct Acting Antiviral (DAA) Therapy The pharmacokinetics of tacrolimus may be impacted by changes in liver function during DAA therapy, related to clearance of HCV virus. Close monitoring and potential dose adjustment of tacrolimus extended-release capsules is warranted to ensure continued efficacy and safety [see Dosage and Administration ( 2.3 , 2.4 )] . 7.3 Cannabidiol The blood levels of tacrolimus may increase upon concomitant use with cannabidiol. When cannabidiol and tacrolimus extended-release capsules are co-administered, closely monitor for an increase in tacrolimus blood levels and for adverse reactions suggestive of tacrolimus toxicity. A dose reduction of tacrolimus extended-release capsules should be considered as needed when tacrolimus extended-release capsules is co-administered with cannabidiol [see Dosage and Administration (2.4) and Warnings and Precautions (5.15) ] .
🚫 Contraindications
4 CONTRAINDICATIONS Tacrolimus extended-release capsules is contraindicated in patients with known hypersensitivity to tacrolimus [see Adverse Reactions ( 6.2 )] . Known hypersensitivity to tacrolimus. ( 4 )
